IMPROVEMENT IN RAILWAY RAIL-JOINT.

The :Schedule referred to in these Letters Patent and part of the' sameTo all whom it may conce/rn:

Be it known that I, EDMUND l?. DWIGHT, of the city of Philadelphia, iniVthe State of Pennsylvania, have invented a new and useful Improvement inRail- Joints; and Ido hereby` declare the following to be.I f a full,clear, and vexact description ofthe same, which will enable othersskilled in the art to which it appertains to make and use my invention,reference being had'to the accompanying drawing which forms a part".ofthis specification, and inrwhich- Figure 1 is a side View of myyimproved rail-joint; .Figure 2, a transverse section of the same-,taken,on the line l 2, fig.` 1 and- Figure 3, a perspective view ofthestop-washer.

The same letters denote the same parts in all the figures. Y V

A and A' represent the adjacent ends of two contiguous rails. V r

4 B B'aretwo clamps', each constructed so as to embrace :ind support thebases of the rails and with the lower part bent downward to form aliange, as shown at b b. The end of one of these flanges is again bent,Vso as to `form a shoulder or second ange,.which serves as the bea-ringfor the flange of the opposite clamp.

i Theconstruction thus far described is oldan'd well known, but myimprovement upon it consistsin beveling the contiguous bearing. ends ofthe anges, as

shown at az, tig. 2.

Each of the clamps B B is perforated forthe pas-- sage of bolts C. Whenthe bolts are inserted Vinto their position, the head of each bolt bearsagainst the under side of one of the clamps, and a metal block, j',bearing against the under side of theopposite clamp, is then slipped'over the bolt as far as the flange of thevclamp permits. A stop-washeris` then slipped over the end of the bolt and against the'metal block,after which the-nut d is screwed on, and the ends of the washer bentupon the'nnt and block, as shown at i fi',

fig. 3.

In theoperation of these devices, the nut cannot turn without turningthe stop-washer and metal block, whichv latter, as well as the head ofthe bolt, is prevented from turning .by the clamps. By this means-Iprevent the joint from loosening under the jar of passing trains.

4 What I claim as my invention, and desire to secure 'by Letters Patentof the United States, is'

1. T heclamps, 'constructed' each with aange, thc end-of one of whichflanges is formed into a beveled shoulder for the bearing of the beveledend of the oppositeflange.

2. The combination of the clamps, bolt, metal block,

-stop-washer, and nut, when these partsare constructed and arranged tooperate as described. l
